This paper develops an improved equity valuation model that predicts firm's market value using firm's Balanced Scorecard (BSC) metrics. It is developed in response to the declining association between market value and, book value and earnings. A 10-year data of 300 firms listed on Bursa Malaysia Main Market was selected as sample. The data of market value and BSC measures were transformed into their natural log form (ln) in order to obtain normal and compatible data. The model shows that BSC better explains the market value than the conventional models.
